Iran reportedly issued a possible 'operational trigger' to activate 'sleeper assets' overseas after the death of Supreme Leader Ali Khamenei, according to an encrypted message intercepted by Washington.
The message, which was transmitted after the military conflict involving the United States and Israel began, contained directions for 'covert operatives or sleeper assets' and was intended for 'clandestine recipients' who hold the required encryption key.
US officials have increased security and warned of the risk of revenge attacks inside the United States, with counterintelligence experts raising concerns about the possibility of Hezbollah or Hamas cells acting violently in the country.
Leaders of major American cities have also announced stronger patrols around sensitive areas, including places of worship, cultural centers, and schools.
